AI-assisted summary
Description from the seller
Nice piece of rocky meteorite, Rumuruti-type, a piece with original crust and the fantastic chondrules.
Rumuruti chondrites are a very rare type of chondrites. Less than 0.5% of the chondrites are classified as R.
They differ from ordinary chondrites mainly in having most of the metal in the form of sulfides, in being more oxidized, and in containing little iron and nickel metal.
They have a matrix with more dust (about 50%), a higher concentration of trace elements zinc and selenium, and a higher proportion of oxygen-17 than ordinary chondrites.
They are called "R" after the Rumuruti meteorite, which fell on January 28, 1934 in the Rift Valley, Kenya.
Chondrites are the oldest materials in the solar system, with an estimated formation age of 4.550 billion years. They are meteorites that have not undergone differentiation, which is why they contain iron, in this case in small amounts since they are LL-type.
Most of them come from the asteroid belt located between the planets Mars and Jupiter.
The characteristic feature of chondrites is the presence of chondrules, small, millimeter-sized spheres composed largely of silicates.
The standard model for their initial formation is that they form during the condensation of the solar nebula from cosmic dust.
Chondrites are the earliest building blocks from which planets form.
At Expometeoritos, we handle outreach, talks, workshops, analyses, classification, and exhibitions of meteorites.
Seller's Story
We search for pieces of the cosmos
to put the universe in your hands.
At Expometeoritos we are dedicated to visiting the most inhospitable corners of the planet in search of meteorites and all those elements (Impactites, Suevites, Tektites, etc.) that attest to what the universe around us is like and how it works.
We are adventurous, curious and restless by nature and thanks to this project we can bring the secrets of the cosmos closer to all of you in a different way.
We organize informative talks, exhibitions, we analyze and classify, cut and polish meteorites and, in addition, we offer you the best pieces so that you can get hold of them and have a piece of the universe in your own home.
Our commitment is complete and we want you to have all the guarantees and confidence, that is why all our pieces are certified and an analysis of their chemical composition is also included if the value of the piece exceeds €300. The analysis is carried out in our facilities by X-ray spectrography.
The pieces will be sent by express service UPS 24/48 hours
